To all whom it may concern."

y Be it known that I, HORACE E. SMYTHE,

a citizen of the United States, residing at Oakmont, in the county of Allegheny and 5 State of Pennsylvania, have-invented or discovered new and useful Improvements in Furnace-Feeding Apparatus, of .which the following is a specification.

I M invention relates to apparatus for feedin oose material into gas-producers, and other types of'furnaces, and has for its object to produce a feeding apparatus which shall do iver material into gas-producers or the like in small quantities and uniformly to all parts thereof.

My invention may also include means for maintaining a gas-seal in the hopper during the feeding'operation and for a itating the material so that it will be fed-with certainty.

Other objects will appearhereinafter.

. Referring to the drawings accompanying this specifioatiom-Figure 1 is a vertical section of a hopper embodying. my improve-- ments, the section being taken longitudi-' nally through the axis of the feed drum 18; Fig. 2, a vertical section taken transversely of the feed-drum; Fig. 3,'a plan; Fig. 4, a sec- V tion on the line 4-4 of Fig. 2; Fig. 5,'a view of the upper part of Fig. 2 with the feeding drum in a di erent position; and Fig. 6, a perspective of the guard for the bearing of the agitator rolls.

On the drawings, 1 designates the top plate of a gas-producer or other apparatus into .whichit is desired to feed loose material. The plate 1 has the opening 2in which is the lower end of' the hopper-casing 3, secured to the plate 1 by 'means\ of screws passed through the flange 4 on the casing into the upstanding, flange 5 on the said plate.

The-casing 3 is made of\ three vertical sec- The top "section, which is ared upwardly,

has the annular groove 9 at its upper end in j which the cover 10 may be sealed gas tight I tions 6, 7, and 8 secured tofigether by bolts.

. by'water. or sand in the well'known manner. The lower contracted end of the section 6- registers with the inlet 11Qat the top of the section 7. Horizontal rollers 12, of which there may. be any desired number, have ner surfaces of the up er ends of the section 7.. These slots exten entirely to the top of the section for convenience of inserting and removing the rollers. The upper section 6 Fig. 1.

on whic covers the open ends of the slots as shown in:

The slots are elongated vertically to permit the rollers to have vertical movement. To prevent the coal from ente the slots abovethe journals of the rollers,-

provide guards which have-vertical fis es: 14 lying close against .the inner faces of t c section 6, these flanges havin their u per ends beveled as shown. The lower on s of the flanges rest on the reduced ends or jour-- nals of the n'ollers and areheldfrom moving inwardly toward the center of the ho per by. their engagement with the shoul era 15 formed at the junction of the rollers with their saidjournals. v The flanges 14 -ca'rry outwardly extending portions 16 which lie on rovided'with the said inlet 11 at the top 0 thesection 7'-' and the outlet 17 at the bottom of the sec j,.

tion 8. In the said drum-shaped interior of the hop er is. the central horizontal shaft 25,

ii the feed-drum 18 is mounted. The drum has a series of pockets 19 parallel with the shaft. These pockets have the blades or arms 20 and 21 extending from the body or centerof the drum to or in proximity to the inner wall 22 of the sections 7 and 8. The

blades 20 extend into contact with the said wall 22, but the blades 21 have between their outer edges and the wall 22 the rollers 24 on the said wall 22 and'the outer edge of the.

blades with which they are associated. The shaft 25 is provided with the gear 26 meshing with the pinion 27 on. he shaft 28 carrying the handle 29, but it wi 1 be understood that this shaft may be driven by steam or other power. The shaft 28 is shown mounted on the standard 30.

The rollers 12 are so located that the blades 20 and the rollers 24 will engage, lift and rotate them as the drum 18 rotates. The number of the blades will be such as to alwa s maintain at least one at each side of t e opening 17 and between the opening 11 and Y the opening 17, so that no gas from the producer can escape durin drum 18. All the blades may be with or without bearing 23 and rollers 24, or theymiaiy be partly, with and partly without ro ers the rotation of the Below the drum 18-, the soot on 8 oi the hoop 21, 1" 3 is made preferably eironle The spaces between adjacent per it-ions and between the leteralpertitions the sides? the casing ere partially closed et} their lower edges by the downwardly inolined floors 82 which spring alternately from opposite sides or" the easing.
